  • The Korean origin sunflower (Helianthus Annus Linn.) seed of netural lipid were analysed by thinchrography, High performance liquid chromatography, preparative Thinlayer and Gas liquid chromatography. 1) The seed oil triglyceride components were conveniently separated based on their degree of unsaturation by employing the chromatography on silica gel sintered rod impregnated with 12.5% silver nitrate. Sunflower seed oil was composed of triglyceride, especially trilinolein 57. 74% triolein 25.28%, tripalmitin 7 55% ana tristearin 9.43% by a thinctrography. 2) The fatty acid compositions of seed oil have been determined by a high performance liquid chromatographic analysis using a ALC/GPC 244 type from Waters Association (Japan) with ${\mu}$ Bondapak FFAA column. It contained stearic acid 8.59%, oleic acid 27. 19%, palmitic acid 7.50% and linoleic acid 56.72% respectively. 3) The composition of sterols were determined by a preparative Thinlayer and Gas liquid chromatographic analysis. It was noted that sitosterol was the major sterol in the Korean sunflower seed. The results showed that contents of sterols were cholesterol trace, campesterol $13_.^{22\sim}13.9%$, stigmasterol $13.8{\sim}14.1%$, If, sitosterol $58.4{\sim}60.7%$, ${\vartriangle}^7$-stigmastenol $10.2{\sim}10.5%$ and ${\vartriangle}^{7,24(25)}$-stigmastenol $3.6{\sim}3.8%$ by method of planimetry and triangulation.

  • This study was carried out to investigate the effect of the feeding mixture of linseed oil, rich in n-3 PUFA and the sunflower seed oil, rich in n-6 PUFA on the lipid metabolism in the dietary hyperlipidemic rats. After male Sprague-Dawley rats were induced hyperlipidemia by feeding the diet containing lard, butter and cholesterol for 3 weeks, then they were fed with the diet containing lard 3.0 % and butter 12.0% for control, the mixture in different proportion of both linseed oil and sunflower seed oil and antihyperlipidemic drugs for 2 weeks. Analysis of the lipid component of the serum showed following results. Concentration of total cholesterol in serum was significantly lower in the other groups except group 2 (lard 3.0 % + olive oil 12.0%) than in the control group , especially in groups 3 (cholestyramine 2.0%) and 5 (lard 3.0% + linseed oil 12.0%). HDL-C and the ratio of HDL-C to total cholesterol concentration were higher in groups 1, 3, 5 and 9 (lard 3.0% + sunflower seed oil 12.0%) , while the atherosclerotic index was low in groups3, 5. Concentrations of free cholesterol and choesteryl ester in serum were significantly lower in the other groups except group 2 than in the control group, especially lower in grop 5. Concentration of LDL was significantly higher in group 2 while it was remarkably lower in groups 3 and 5, while those of triglyceride in groups in 3 and 4 (lipraroid) were significantly higher than in the control groups. From the data on concentration of total choelsterol , HDL-cholesterol, LDL, phospholipid and triglyceride in serum, the results suggested that the feeding mixed with 3.0% lard and 12.0% linseed oil or 2.0% cholestyramine were most effective for the improvement of the serum lipids.

  • Eighteen water buffalo calves of Nili-Ravi breed (about 15 months age and of $147{\pm}12$ kg average body weight and mixed sex) were used with six animals on each treatment. All the animals were fed long wheat straw for ad libitum intake as the basal ration. Animals in group-I were supplemented with ad libitum amount of urea molasses block having cotton seed meal (CSMB) while the animals in group-II were supplemented with ad libitum urea molasses block containing sunflower seed meal (SFMB) and group III animals were supplemented with a fixed amount of commercial concentrate feed (CCF). The experiment lasted for a period of 80 days (April to June). Results revealed a significantly decreased total feed intake (wheat straw+supplements) in group-III ($1,666{\pm}52$ g/h/d) as compared to group I ($2,299{\pm}194$ g/h/d) and group-II ($2,193{\pm}230$ g/h/d). Average daily supplement intakes were $891{\pm}87$; $666{\pm}104$ and $593{\pm}0$ grams per head in group I, II and III, respectively. Supplement intakes among groups were different (p<0.05). Average daily body weight gains (g/h) were $214{\pm}25$, $174{\pm}23 $and $183{\pm}24$ for group I, II and III, respectively. Feed conversion ratio (FCR) was found to be $10.74{\pm}1.12$, $12.60{\pm}0.88$ and $9.90{\pm}1.33$ grams for group No. I, II and III, respectively. The economic net benefit of live weight gain of calves were 7.63, 6.11 and 7.33 rupees/h/d for group No. I, II and III, respectively. Thus SFM can replace CSM and urea molasses blocks can replace commercial concentrates as supplement to basal ration of wheat straw.

  • Background: An important consideration for the risk assessment of transgenic plants is their overwintering potential in a natural ecosystem, which allows the survival of the seed bank and may lead to seed reproduction. Here, we investigated the overwintering of sunflower (Helianthus annuus L.) seeds in the laboratory (temperatures: -5, -1, 5, and 10℃) and in the field (burial depth: 0, 5, 15, and 30 cm) as a case study to examine the invasiveness of transgenic crops. Results: Sunflower seeds germinated when incubated at 5℃ and 10℃ for 2, 4, 6, and 12 weeks but not when incubated at -5℃ or -1℃. However, the seeds incubated at -5℃ or -1℃ germinated when they were transferred to the optimal germination temperature (25℃). Up to 16.5% and 15.0% of seeds were dormant when cultured at sub-zero temperatures in a Petri dish containing filter paper and soil, respectively. In the field trial, soil temperature, moisture, and microbial communities differed significantly between soil depths. Germination-related microorganisms were more distributed on the soil surface. Seeds buried on the surface decayed rapidly from 4 weeks after burial, whereas those buried at depths of 15 cm and 30 cm germinated even 16 weeks after burial. No dormancy was detected for seeds buried at any depth. Conclusions: Although sunflower seeds did not overwinter in situ in this study, we cannot exclude the possibility that these seeds lie dormant at sub-zero temperatures and then germinate at optimal temperatures in nature.

  • 페스토는 잣, 해바라기씨, 호박씨, 호두, 아몬드를 넣고 제조하여 항산화성(총 폴리페놀, 총 플라보노이드, 전자공여능)과 관능검사를 실시하였고, $4^{\circ}C$에서 20일간 저장하면서 색도, pH, 점도, 총 균수를 측정하였다. 페스토의 총 폴리페놀과 총 플라보노이드 함량이 높을수록 항산화력이 높았으며, 일반적으로 사용되는 잣보다 해바라기씨나 호두를 이용할 때 바질 페스토가 더 기능성이 있을 것으로 사료된다. 특성 차이 검사 결과, 색의 강도, 견과류 맛, 씁쓸한 맛, 까끌까끌 정도와 후미는 AMP(아몬드)가, 기름진 맛, 걸쭉한 정도는 WNP(호두)가 유의적(p<0.001)으로 강하다고 평가되었고, 윤기, 바질 냄새, 견과류 냄새, 바질 맛은 견과류 종류에 따른 유의적인 차이가 없었다. 기호도 검사 결과, 냄새의 기호도는 유의적인 차이를 보이지 않았고, 외관, 맛, 텍스처 및 전체적인 기호도는 잣을 이용한 PNP와 해바라기씨를 이용한 SSP가 가장 높았다. 바질 페스토는 저장기간이 길어질수록 a, b값과 점도가 증가한데 반해, L값과 pH는 감소하였다. 총 균수는 저장 기간이 길어짐에 따라 증가하였다가 어느 일정 시점이 지남에 따라 다소 감소하였으나, 본 연구의 총 균수는 식품의 오염에 해당하지 않으므로 미생물학적으로 비교적 안정하였다. 따라서 페스토 제조시 잣 이외에도 해바라기씨를 이용하는 것에 대한 가능성이 확인되었다.

  • Conidia of Beauveria bassiana ARSEF-7060, produced in millet amended with plant oils such as sunflower, corn, or cotton seed oil, were exposed to $45^{\circ}C$ of wet heat for 90 min. Conidia from millet+corn oil medium had the highest thermotolerance [$LT_{50}$ (median survival time): 45.7 min]. The mycotized millet grains were coated with each of the same plant oils as a granular formulation and subjected to $50^{\circ}C$ of dry heat for 8 h. Corn oil coating ($LT_{50}$: 8.68 h) was superior to sunflower and cotton seed oil coatings, suggesting the feasibility of using corn oil to increase conidial thermotolerance.

  • This study was conducted to evaluate the effect of dietary supplementation with rice bran, flax seed, or sunflower seed to finishing native Korean cattle (Hanwoo) on growth performances, carcass characteristics, fatty acid composition, free amino acid and peptide contents, and sensory evaluations of Longissimus muscle (LM). A total of 39 Hanwoo steers (average age of 22.2 mo and average body weight (BW) of 552.2 kg) were randomly divided into Control, rice bran (RB), flax seed (FS), or Sunflower seed (SS) groups. The steers were group fed for 273 d until they reached an average age of 31.2 mo. Final BW was 768.2, 785.8, 786.2, and 789.0 kg, and average daily gain was 0.79, 0.85, 0.82, and 0.84 kg for the Control, RS, FS, and SS groups, respectively (p>0.05). Fat thickness of the FS group (19.8 mm) was greater (p<0.05) than that of the other groups. Final yield grade converted into numerical values was 2.0 for the RB group, 1.7 for the Control and SS groups, and 1.4 for the FS group. Marbling degrees for the Control, SS, RB, and FS groups were 5.3, 5.1, 4.7, and 4.6, respectively. Percentages of palmitic acid ($C_{16:0}$), stearic acid ($C_{18:0}$), and arachidic acid ($C_{20:0}$) in the LM were not different among the groups. Palmitoleic ($C_{16:1}$) acid was higher (p<0.05) in the SS group. The concentration of oleic acid was highest (p<0.05) in the Control group (47.73%). The level of linolenic acid ($C_{18:3}$) was 2.3 times higher (p<0.05) in the FS group compared to the other groups. Methionine concentration was (p<0.05) higher in FS (1.7 mg/100 g) and SS (1.2 mg/100 g) steers than in the Control or RB groups. Glutamic acid and ${\alpha}$-aminoadipic acid (${\alpha}$-AAA) contents were (p<0.05) higher in the FS group compared to the other groups. LM from the FS group had numerically higher (p>0.05) scores for flavor, umami, and overall palatability in sensory evaluations. In conclusion, supplementation of flax seed to diets of finishing Hanwoo steers improved sensory evaluations which might have been caused by increases in flavor related amino acids such as methionine, glutamic acid and ${\alpha}$-AAA and peptides, anserine and carnosine, and their complex reactions.
